DEPR: https://github.com/openedx/edx-platform/issues/36429 This change removes the course_sock and related API data. The UI it removes is on the Legacy Courseware pages which have also been replaced and have their own [deprecation ticket](https://github.com/openedx/edx-platform/issues/35803) Before this can be merged, we will need to update the frontend-app-learning MFE to no longer consume the `can_show_upgrade_sock` attribute. BREAKING CHANGE: CourseHomeMetadata, ProgressTab, OutlineTab and VerifiedMode APIs will no longer have a `can_show_upgrade_sock` attribute.
